Nice quality! This UNO Advanced is a very high quality stem, it differs from other simple UNO stems with hardened metal, also the removable front cover (that attaches to the stem with 4 bolts) is fully made from metal without holes, so it's more durable too that in other UNO stems. I compared weight of my old original MTB GIANT stem with this stem using kitchen weight, and also checked the weight of bolts and removable cover - they occured to be nearly the same (bolts the same). That means that producers are not greedy about metal and it should be durable. Moreover, I was fascinated that fo each bolts groups (1-x2 , 2-x4) producer wrote what tightening torque amount is required!
Quality product.
